The Reggia‐Spencer Microwave Phase Shifter

摘要

The essential properties of the wave‐guide phase shifter reported by Reggia and Spencer are explained by means of a composite phenomenological model which incorporates the two dominating effects: the elliptic wave‐guide symmetry and a dielectric wave‐guide effect. The model provides an advantageous starting point for more precise calculations, as well as a qualitative guide to further device development. It also sheds further light on Faraday rotation and its associated interference effect under conditions of elliptic symmetry.
